Fresh Lemon Bath Bombs

Here at Ruffles and Rain Boots, we are all about that relaxation in the tub. Even if it’s just for long enough to let my muscles loosen in my shoulders and my toes uncurl. Spending 15 minutes in the tub is so precious. And making bath bombs so I have an excuse to rest and feel the fizz? Precious beyond reason right now. Plus, zesty flavors swirling around me, making me feel like a sauté? Ah-mazing. LOL!


In all seriousness, though, I am keeping these ridiculously zesty lemon bath bombs to myself. They’re perfect for gifts, sure, but the truth is that I am loving the way they make the bathroom smell–and me too. If you’re ready to get all zesty, let’s get started.

Tips to Make Lemon Zest Bath Bombs

  • These lemon bath bombs are so simple but they smell so bright and fresh. All you do is follow the directions below and you won’t be disappointed.
  • I always recommend drying your bath bombs for at least 24 hours so you get the most fizzy for your effort. Plus, when they dry for that long, if the mixture accidentally got a bit wetter than absolutely necessary, you’ll still get your fizz.
  • To make sure your DIY Lush bath bombs remain at their top-fizziness peak, always store them in an air-tight container. Even, if you’re making them as a gift for a friend or neighbor, keep them in that airtight container.
  • As with any DIY project, it’s on you to put as much fragrance or colorant into your lemon zest bath bombs as you’d like–they’re your bath bombs and it’s your bath. But please, for the love of all the bath bombs, never use food coloring–that’s a guaranteed way to color your skin with a nice shade of whatever AND the bathtub (you don’t want to match you bathtub, come on). So, stick with soap colorant or mica powders to be safe.
  • This lemon bath bomb is made-up of essential oil, citric acid, and a bit of water (with some other stuff but that’s the basic recipe). That’s seriously all there is to it. So, if you’re having trouble getting your bath bombs to hold their shape, they’re probably not wet enough. Just add a little water and try again.
